摘要
To realize perception of local lunar surface under the condition of relative stationary before soft landing during moon discovery, a novel 3-D imaging method is proposed. The method is based on range high-resolution in altitude dimensional and 2-D receiving digital beam forming to radar scene floor. The outstanding feature is this method can realize 3-D imaging without relative motion between radar and target. According to imaging principle, the transmitting waveforms, antenna shape and size has been researched and designed; the choosing of imaging height and stepping size for scene scan were also discussed; the whole imaging processing flow was given and has been simulated using computer. Simulation results indicate that it can obtain 3-D coordinates of strong scattering centers accurately and reconstruct 3-D image of scene successfully.
